Pin Descriptions

Pin Number

Pin Name

Pin Function

1, 3

C1+, C1−

External capacitor connection pins. Recommended external capacitor C1 = 0.1µF (6.3V)

2

V+

Positive supply for TIA/EIA-232E drivers. Recommended external capacitor C4 = 0.1µF (6.3V)

4, 5

C2+, C2−

External capacitor connection pins. Recommended external capacitor C2 = 0.1µF (16V)

6

V−

Negative supply for TIA/EIA-232E drivers. Recommended external capacitor C3 = 0.1µF (16V)

7, 14

T1out, T2out

Transmitter output pins conform to TIA/EIA-232E levels. The typical transmitter output swing is

Ω load to ground. The open-circuit output voltage swings from (V+ − 0.6V)

to V−

8,13

R1in, R2in

Receiver inputs accept TIA/EIA-232

9, 12

R1out and R2out Receiver output pins are TTL/CMOS compatible

10, 11

Tin1, Tin2

Transmitter input pins are TTL/CMOS compatible. Inputs of transmitter do not have pull-up

resistors. Connect all unused transmitter inputs to ground
